Document Summary
Lecture 4: properties and global distribution of water (9/3/20) Poured on the footprint of the us = lake 90 mi deep! (= the distance from charleston to myrtle beach) 0. 02 x 106 cubic miles of fresh, surface water. A tiny sample of a mineral included in a diamond confirms predictions from high-pressure laboratory experiments that a water reservoir is hidden deep in earth"s mantle. 1 to 3 times the size of the oceans! Mantle transition zone, depth of 410-660 km. Surface tension constriction of a fluid to create a film at the surface. Attraction to itself pulls drops into a spherical form and rel. high force needed to break. Water as a solid (ice) is less dense than it is as a liquid. Area of land where all of the surface dains of to the same place (common point) Can be very large or very small. Segments can be categorized by their order in the system.
